Hey everybody. I'm brand new to this site and it seems like he has a lot of good information with a lot of smart guys so this is where I decided to ask for help. I finally have the speaker's ivw wanted forever which are two 12 inch Sundown Audio sa 12 2 ohm and for the last 3 days I've been trying to figure out how to build my own box to speak for them or to make them sound the best I've been using calculators and all the information I got off of Sundown audio.com and I can't for the life of me figure out how to put it all together to get a cut sheet out of it. Its going in a Dodge Dakota quad cab which I took out the back seat and build a platform so I have pretty much 48×24×24 space to use which is plenty. On Sundown audio.com it says that the specs are supposed to be tuned to is 1.5-2.0 ft^3 @ 35 Hz and if somebody could just tell me how to get to the point where I could use all this information to just get it cut sheet or if somebody knows a faster way and just gives me the measurements for a cut sheet and I can just build the box for the 2-12 I would really appreciate it. And if it's this hard to understand it's because I'm using talk to text. Thanks everybody in advance who helps
